Description

Technical Field

[0001] The utility model belongs to the technical field of liquid nitrogen tanks, in particular to a cell storage liquid nitrogen tank. Background Art

[0002] Liquid nitrogen tanks are the basic equipment for transporting hematopoietic cells in the current biotechnology and pharmaceutical fields. Liquid nitrogen is added to the inner cavity of the liquid nitrogen tank, and the inner cavity is kept at a low temperature, so that it can be used to store frozen bags containing hematopoietic cells and keep the hematopoietic cells active.

[0003] In the existing technology, when taking cells out of the liquid nitrogen tank, it is necessary to manually open the tank lid and then reach into the liquid nitrogen tank to take the cells out. During the taking and placing process, although the workers wear protective gloves, there is still a risk of frostbite caused by their arms touching the inner wall of the liquid nitrogen tank.

[0004] Therefore, in response to the above problems, a cell storage liquid nitrogen tank is proposed. Utility Model Content

[0005] In order to make up for the shortcomings of the existing technology and solve the problem that when taking cells out of the liquid nitrogen tank, the tank lid needs to be opened manually and then the hands need to be put into the liquid nitrogen tank to take out the cells. During the taking and placing process, although the workers wear protective gloves, there is still a risk of frostbite caused by the arms touching the inner wall of the liquid nitrogen tank. A cell storage liquid nitrogen tank is proposed.

[0012] Beneficial effects of the utility model:

[0013] The utility model provides a liquid nitrogen tank for cell storage. When a storage tube needs to be taken out, the sealing cover is first taken out from the access opening. By starting the second motor, the rotation of the second motor drives the second rotating shaft to rotate, thereby rotating the supporting plate so that one of the slots is in a position corresponding to the access opening. At this time, by starting the cylinder, the cylinder rod extends downward, thereby making the clamping assembly close to the storage tube. When the lower end of the clamping block contacts the tube cover, the first motor is started, the first motor rotates, thereby driving the first rotating shaft to rotate. Through the meshing action between the first bevel gear and the second bevel gear, the bidirectional screw is rotated. The rotation of the bidirectional screw drives the two clamping blocks to approach each other, thereby clamping the handle part on the tube cover. Then the cylinder retracts, and the storage tube is taken out of the tank body. The whole process does not require the staff to put their hands into the tank body to take out the test tube.

[0014] The utility model provides a liquid nitrogen tank for cell storage. When the second motor rotates, the angle of each rotation of the supporting plate is fixed, and only one storage tube can be taken out at a time. When the storage tube is taken out, the outflow of liquid nitrogen is less, which can effectively save liquid nitrogen. BRIEF DESCRIPTION OF THE DRAWINGS

During operation, the storage tube 5 is used to place cells. When the storage tube 5 needs to be taken out, the sealing cover 12 is first taken out from the access port, and the second motor 4 is started. The second motor 4 rotates to drive the second rotating shaft 41 to rotate, thereby rotating the support plate 7 so that one of the slots is in a position corresponding to the access port. When the second motor 4 rotates, the angle of rotation of the support plate 7 is fixed each time, and only one storage tube 5 is taken out at a time.

[0031] Working principle:

[0032] When the utility model is in use, the storage tube 5 is used to place cells. When the storage tube 5 needs to be taken out, the sealing cover 12 is first taken out from the take-in and put-out port, and the second motor 4 is started. The second motor 4 rotates to drive the second rotating shaft 41 to rotate, thereby rotating the supporting plate 7 so that one of the slots is in a position corresponding to the take-in and put-out port. When the second motor 4 rotates, the angle of rotation of the supporting plate 7 is fixed each time, and only one storage tube 5 is taken out at a time. When the storage tube 5 is taken out, the amount of liquid nitrogen flowing out is less, which can effectively save liquid nitrogen; at this time, by starting the cylinder 21, the cylinder 21 rod extends downward, thereby making the clamping assembly 3 close to the storage tube 5, and when the lower end of the clamping block contacts the tube cover 6, the first motor 32 is started, and the first motor 32 is driven to rotate. The machine 32 rotates, thereby driving the first rotating shaft 321 to rotate, and the meshing action between the first bevel gear 311 and the second bevel gear 322 causes the bidirectional screw rod 31 to rotate. The rotation of the bidirectional screw rod 31 causes the two clamping blocks to approach each other, thereby clamping the handle 61 part on the tube cover 6, and then the cylinder 21 retracts to take the storage tube 5 out of the tank body 1. The whole process does not require the staff to reach into the tank body 1 to take out the test tube, which solves the problem in the prior art that when taking cells out of the liquid nitrogen tank, the staff need to manually open the tank cover and then reach into the liquid nitrogen tank to take out the cells. During the taking and placing process, although the staff wears protective gloves, there is still a risk of frostbite caused by the arm touching the inner wall of the liquid nitrogen tank.
